Dear STATA community
I am looking to study the occurence of stroke in the presence of death as competing risk in a pooled patient cohort. One way to account for competing risks is Fine-Gray modelling, which is implemented in STATA with the stcrreg command.
Since the patients in my pooled dataset originate from separate cohorts, i would like to somehow account for potential differences among the different cohorts in my model. In the case of Cox proportional hazards regression, one might introduce stratification to cohorts or shared frailty for cohort in the model to adress this. However, the stcrreg command does not seem to give the option to use strata or shared frailty.
Hence my question: Is there a way to introduce strata or shared frailty to the Fine-Gray model, or some other way to account for potential differences among the different cohorts in the Fine-Gray model?
Many thanks for any insight
